Fairy Pairing

‘Park Gyu-chan’ lives a life of debauchery and one-night stands. Today again, Gyu-chan gets drunk as usual and wanders around clubs in search of his ideal partner. He finally meets a beautiful blonde woman with big breasts and spends the night with her. When he wakes up in his bed, holding his head dizzy from drunkenness, he witness the unbelievable sight of a winged man sticking something fierce into his anus. The man introduces himself as the fairy 'Mon' and asks Gyu-chan to save the fairy world... But... "The way to save the fairy world is to cum in my anus?"
